Configuration and calibration programming is entered with three hidden
keys—keys not intended for end-user access. A hidden programming key
accesses the set-up modes, and two hidden arrow keys select and enter
data within the set-up modes. The hidden keys also access the internal raw
counts value and the software release number. Figure 1 below shows the
locations of the hidden keys on the Model 615/XL.

The three hidden keys are touch-sensitive, as are all the keys on the Model
615/XL. However, unlike other keys, the three hidden keys do not have key
faces. These keys are hidden from end users because access to the set-up
modes is intended only for trained technicians who use this service manual.

Determining Axle Sizes

To use the configuration code chart in Table 2 for determining an appropri­ate configuration code for your weighing system, you must first know the
calibration axle size of the Weigh Bar(s) or alternative weight transducer(s).
Physical axle size (the measured diameter of a bar) and calibration axle size
(the measurement marked on a bar) are not the same for some Weigh Bars.
Read about the following combinations of physical axle sizes and calibration
axle sizes, and follow the guideline that applies to your bar(s):

• If your weight transducer measures five-eighths inch (5/8") in diameter,
but is marked with a calibration axle size of 2-1/4" D (Dual), use data
shown in Table 2 for a five-eighths-inch (5/8") bar.

• If your weight transducer measures one inch (1") in diameter, but is
marked with a calibration axle size of 2-1/8", use data shown in Table 2
for a one-inch (1") bar.

• For weight transducers which have a physical axle size of either five­eighths inch (5/8") or one inch (1"), but which are marked with a
calibration axle size other than 2-1/4" D or 2-1/8" respectively, use data
shown in Table 2 for Custom Sensitivity and Capacity x Increment.

• For all other weight transducers: Whether the physical axle size of the
bar and the calibration axle size marked on the bar do or do not match,
use data shown in Table 2 for the calibration axle size marked on the
bar.

Determining a Configuration Code

Table 1 is an example of a set of configuration choices for a Model 615/XL
weighing system. Table 1 shows you how selections for the Model 615/XL’s
configurable parameters would be represented by a configuration code of
5121, according to the configuration code chart in Table 2. You can see that
each digit in the code represents a parameter, and the value of each digit
represents a selection for that parameter as shown in Table 2.

A Sample Set of Configuration Choices

Its Corresponding Configuration Code (5121)

Parameter Represented Selection Config.

Axle size 2nd digit 2-1/8" 5
Capacity X increment size 3rd digit 20k x 2 1
Auto zero tracking 4th digit ±1.0 division 2
Units of measure and
Capture mode 5th digit Ib/On 1

Configuration code 5121 uses only the

2nd, 3rd, 4th and 5th of five available digits.

The sample configuration code, shown in bold type in Table 1, may be
written horizontally, with digit places numbered, as follows:

Sample configuration code: 51 2 2
Digit place #s: 1 2 3 4 5

Remember, a four-digit configuration code uses digit places #2, #3, #4, and
#5, but not #1. Digit place #1 is to be used only if the configuration code has
five digits. Five digits are required only for bars with calibration axle sizes of
3-1/8 inches and 4 inches and when custom sensitivity (with capacity x
increment) is appropriate (See Table 2).

Determining the Custom Sensitivity Rating

This procedure allows you to configure a sensitivity rating for a weight
transducer that is not referenced in Table 2. You may configure another
manufacturer’s weight transducer for interface with the Model 615/XL.
Before starting the keying procedure for configuring custom sensitivity, you
must verify three facts about the transducer(s) being used:

• Trade name of the transducer

• Sensitivity rating of the transducer

• Capacity x increment size of the transducer

Trade Name of the Transducer

To configure custom sensitivity for Weigh-Tronix Weigh Bars, see the next
subsection, Sensitivity Rating of the Transducer.

To configure for transducers from manufacturers other than Weigh-Tronix,
refer now to instructions located in the Programming Appendix. If you find
that custom configuration of sensitivity is required for your transducer(s),
return to this section and proceed to the next topic.

Sensitivity Ratings of the Transducer

1. Determine the sensitivity rating, that is, the mV/V output at full capacity,
for the weight transducer(s) you are using. You will probably find this
information stamped or printed on the transducer.

2. Call the factory at 1-800-458-7062 for help in determining the Model 615/
XL sensitivity rating for your transducer(s). Because a number of
different types of bars are used by various manufacturers of weight
transducers, it is impossible to provide generic instructions on determin­ing Model 615/XL sensitivity ratings for all the weight transducers
available.

3. Write down your calculated sensitivity rating here us­ing the following format:

n. nnnnnnn = your sensitivity rating
1 2345678 = digit places

You may key in a mV/V value of up to eight digits. Selection range for
sensitivity is from 0.075 to 6.0 mV/V. Keep your notation handy for entry
in steps 5, 6, 7, and 8 of the following keying procedure.

Capacity x Increment Size of the Transducer

4. Refer to Table 5 and locate a capacity x increment size combination that
is appropriate for your Model 615/XL.

5. Look on the right end of Table 5, and identify the number of the row in
which your selected capacity x increment size is located. Then write
down that row number here: __________________

You will need this row number in step 11 of Keying In the Custom
Sensitivity Rating.

Circuit Descriptions

Main Printed Circuit Card

This printed circuit card contains the

• Power Supply

• Analog-To-Digital Circuitry

• Microprocessor Circuitry

• Display Circuitry.

Power Supply

To prevent the unit from turning
off below 10 volts, remove CR5
and C36. When configured this
way, the unit will return to the
Gross mode if it loses power.

This indicator, which is energized by 10 to 18 vdc in reference to a NEGA­TIVE GROUND utilizes one five amp fuse mounted on the bottom of the
chassis for current protection. (Systems with a positive ground are modified
by cutting jumpers from E11 to E12 and E9 to E10. Then install jumpers
from E9 to E12 and E10 to E11.)

The circuit card receives power from the fuse at P2 and is protected against
high voltage transients with varistor RV1.

Input voltage is monitored by 16 volt zener diode VR2. If the voltage across
VR2 exceeds 16 vdc, Q3 will turn “ON” holding the power circuitry in the
“OFF” condition. In addition, if the input voltage drops below 10 volts DC,
PA7 disables the power circuitry by outputting a low signal.

A “Power On” command is generated when the ON key is pressed. This
turns Q5 on and provides a low signal to +8v regulator (u18) pin1 enable
input. When the power is turned off, the Q5 turns off, the Q4 turns on and a
high signal disables (U18) the +8 regulator and turns it off.

20

Model 615/615XL Indicator Service Manual

The -7.5 vdc supply voltage is established by U7, a voltage convertor. This
device inverts the input voltage to a -7.5 vdc level.

The +5 vdc voltage is provided by U8, a 7805 regulator.

As soon as the +8 volt power supply voltage is present, Q2 turns on which
turns on the DS2 and DS3 LEDS

Analog to Digital
Circuitry

The analog-to-digital circuitry consists of two weight voltage amplifiers (U1
and U2), a reference amplifier (U3), an analog switch (U4), switch control
logic gate (U14C), a dual slope integrator (U5), and a comparator (U6).

An 8 vdc excitation voltage is supplied to the weight sensors from P1 pins 1
and 6. The millivolt signal received back from the weight sensors enters the
analog-to-digital circuitry at P1, pins 3 and 4.

This millivolt signal is amplified and filtered by U1 and U2 to establish the
amplified weight voltage (0 to +9 vdc) at U2 pin 6. This weight voltage is
then provided to U4 pin 5. A logic low during the weight voltage interval at
U4 pin 1 enables the amplified weight voltage to be received by the dual
slope integrator (U5). Starting at zero volts, the integrator capacitor (C20)
charges at ramp angle directly proportional to the amplified weight voltage
but of opposite polarity. As the amplified weight voltage increases, the
integrator output ramps more in the negative direction.

The voltage received from the sense lines enters the analog-to-digital
circuitry at P1 pins 2 and 5. This sense voltage establishes a reference
voltage of -9 vdc at U3 pin 6. The reference voltage is applied to U4 pin 10.

After the integrator capacitor has been charged for a fixed period of time,
the Weight Voltage Interval, U4 pin 1 goes high. U14 applies a logic low to
pin 14 of U4 which allows the reference voltage to be applied to the integra­tor. Since the reference voltage (-9 vdc) is of opposite polarity to the ampli­fied weight voltage, it causes the integrator output to ramp back toward zero.
(This period of time is known as the Reference Voltage Interval.)

While the integrator output is ramping back to zero, the comparator (U6)
signals the microprocessor to record this period of time in clock pulses. The
microprocessor uses this number of pulses to calculate the amount of
weight on the scale.

When the integrator reaches zero, the comparator output goes low which
triggers U14C to remove the logic low at U4 pin 14 completing one analog­to-digital cycle.

This analog-to-digital conversion repeats at a frequency of 30 hertz.

Model 615/615XL Indicator Service Manual

Microprocessor
Circuitry

The Microprocessor Circuitry consists of a Motorola MC68HC11A1 8-bit
microprocessor IC (u11), a 74HC573 tristate latch (U12), a 27C128 EPROM
(U13), and various other components.

The microprocessor features on chip memory 256 bytes of RAM, 512 bytes
of EEPROM, along with a Computer Operating Properly (COP) watch dog
system.

A 2 MHZ internal clock is contained in the microprocessor and is controlled
by an external crystal (Y1). Output (ECLK) from this clock provides timing
reference for the EPROM (U13), and input to voltage monitoring circuit U9.

The microprocessor communicates with Analog-to-Digital switch control
logic gate U14 through ports PA2 and PA6. Through U14, the timing refer­ence for the Reference Voltage Interval and Weight Voltage Interval are
provided.

The switches on the front panel receive a signal from ports PD2-PD5 on the
microprocessor and they are monitored for an electrical change by ports
PE0PE3 on the microprocessor.

As signals are received by the microprocessor, it will send them to the
EPROM (U13) on the address lines A0-A15. The signals will be translated
and held by U12. Once all translating is completed, the microprocessor will
enable U12 to return the new information on data lines D0-D7 to the micro­processor. Then, the appropriate device will receive a signal from the
microprocessor.

The Computer Operating Properly (COP) watch dog system in the micropro­cessor detects errors introduced by electromagnetic interference. If an error
is detected, the microprocessor is reset and operation continues. When the
indicator is powered up, the momentary displayed "hi" message, indicates
the watch dog system is active.

If a "hi" message is displayed, the indicator will perform correctly, but will not
be guarded by the COP watch dog system. This may happen when a new
microprocessor IC is installed. The COP watch dog system can be activated
by following this procedure:

• Turn the indicator OFF jumper P7-1 to P7-2 and P6-1 to P6-2

• Turn the Model 615/XL ON for a few seconds

• Turn the Model 615/XL OFF

• Remove the jumpers

22

Model 615/615XL Indicator Service Manual

Display Circuitry

The six digit liquid crystal display (DS1) features black segments against a
silver transflective background.

Liquid crystal display driver U15 requires a +5 vdc power supply and two
signal inputs from the microprocessor to function: (1) a 33-bit serial data
input and (2) a microprocessor controlled input. When both of these condi­tions have been met, the display driver will energize the appropriate seg­ments on the display.

Optional RS-232 or Remote
Circuitry

To Install Remote Receiver

Additional circuitry required to provide either an RS-232 communications
interface or a remote display interface requires R49-57, C48-51, U16, U10,
and P6 connector.

The RS-232 transmitter/receiver (U10) internally generates +10v and -10 v
supplies and meets all EIA RS-232C specifications. Through U10, the
microprocessor communicates with peripherals which will accept the follow­ing protocol: baud rate 1200, 1start bit, 8 data bits, no parity, and one stop
bit. The RS-232 communications port supports X-on (HEX 11), X-off (HEX
13_) handshake and responds to an inquire character (HEX 05) print
request.

The invertor/buffer gates (U16) are used in the remote clock, remote data,
remote zero, and remote print lines to provide isolation and assure proper
logic; levels to and from the remote display.

P6 connector provides external access to power supply voltages, RS-232
data lines, remote display drive lines, remote zero lines, and remote print
lines.

After installing PC board assembly P/N 27643-0030 as shown in assembly
section, plug 3 pin cable assembly into P8. This enables user to have
remote zero capabilities within the Model 615/XL. Be sure to match dip
switch selections between receiver card and transmitter.

XM710-L WIRELESS REMOTE INSTALLATION

39

The XM710-L hand-held transmitter provides the ability to remotely perform a zero/reset command and can be installed
in MODEL 615 / 615XL or RD712 / 712XL. The XM710-L wireless remote system is similar to those used on garage door
openers. For selectable security, the transmitter and receiver assembly boards have programmable security code switches.
The eight position switch is used to determine the security code. These can be programmed to a different code, but the
programmed code must match on both the transmitter and receiver.
The unit is shipped from the factory with the following settings:

1, 3, 5, 7 = ON (closed)
2, 4, 6, 8 = OFF (open)

Programming Appendix

To determine an appropriate configuration code for J-Star or Eaton trans­ducers, consult Table 9 for Eaton or Table 10 for J-Star.

Using the Eaton
Configuration Code
Chart (Table 9)

The Eaton Configuration Code Chart (See Table 9) shows you how selec­tions listed below for five configurable parameters would be represented by
a configuration code of 4121. Notice that each digit in the code represents a
parameter, and the value of each digit represents a selection for that param­eter as shown in Table 9: Eaton Configuration Code Chart.

and

Its Corresponding Configuration Code, 4121

Parameter Represented by Selection Config.Code

Capacity x increment size 3rd digit 20K x 2 1

Auto zero tracking 4th digit ±1.0 division 2

Units of measure and

Capture mode 5th digit lb/On 1

Configuration code 4121 uses only the 2nd, 3rd, 4th and 5th of five available digits.

Using the J-Star
Configuration Code
Chart (Table 10)

The J-Star Configuration Code Chart (See Table 10) shows you how
selections listed below for five configurable parameters would be repre­sented by a configuration code of 3121. Notice that each digit in the code
represents a parameter, and the value of each digit represents a selec­tion for that parameter as shown in Table 10: J-Star Configuration Code
Chart.
